YAML to TOML Converter Online
Runs 100% in your browser — your files never leave your device.
Moving a config from a YAML world into a TOML one — Cargo.toml, pyproject.toml, Hugo sites — usually means rewriting by hand. Paste your YAML and get equivalent TOML out, routed through JSON so every nested table and array survives. Errors in the source YAML are flagged inline.
How it works
- 1
Paste your YAML
The TOML output follows as you type.
- 2
Review tables and arrays
Nested structures become TOML tables automatically.
- 3
Copy the TOML
One click copies the converted configuration.
